  • audio data and video data e.g. movies
  • video data e.g. movies
  • the amount of storage capacity available on optical discs is limited, and thus, many types of programs (e.g. movies, television programs, video images, and other audio-visual shows) which have long durations cannot be stored on a single optical disc.
  • the user In order to ensure that the optical discs will be reproduced in the proper order, the user must memorize the order in which the discs were loaded into the multidisc player. Alternatively, the user must physically open the trays of the disc changer and view the actual labels of the optical discs to ensure that they are arranged such that the program will be reproduced in its appropriate order. If the user does not execute either of the above procedures, he or she must reproduce the optical discs at random to confirm that the optical discs will be correctly reproduced. However, each of the methods above is very inconvenient.

  • a microcomputer of the multidisc player reads the various information data recorded on the lead-in area 4 of the optical disc. Then, based on such information data, the microcomputer controls various operations of the multidisc player including the manner in which the optical disc will be reproduced.
  • FIG. 3 One embodiment of a multidisc player of the present invention is shown in FIG. 3. Furthermore, various features in FIG. 3 which are analogous to the features shown in FIG. 1 are represented by the same reference numerals.
  • the multidisc player comprises a disc changer 3, a servo system 7, a detector 8, a signal processing system 9, a memory 10, and a microcomputer 11.
  • the disc changer 3 contains various trays 2 for storing optical discs 1 and supplies a selected disc to the servo system 7 in accordance with a first control signal output from the microcomputer 11. Then, the servo system 7 rotates the selected disc 1 in a certain direction and at a particular speed in response to a second control signal output by the microcomputer 11 .
  • the detector 8 comprises an optical pickup (not shown) and an optical pick up transport device (not shown) , detects the data recorded on the selected disc 1, and outputs corresponding reproduced data.
  • the reproduced data comprises audio and video data relating to a particular program as well as information data.
  • the information data comprises reproduction order data which indicates the sequence in which the selected disc 1 is to be reproduced in order to properly reproduce the particular program. Such information data may be located in the lead-in area 4 of the selected disc 1.
  • the signal processing system 9 inputs the reproduced data from the detector 8 and processes such data. Then, the system 9 outputs the resultant video data to a monitor (not shown) and outputs the resultant audio signal to a speaker (not shown). Furthermore, the signal processing system 9 outputs the reproduction order data to the microcomputer 11, and the microcomputer 11 stores such data in the memory 10.
  • FIGS. 4A and 4B show a flowchart of an illustrative procedure by which the microcomputer 11 performs a method for sequentially reproducing a plurality of optical discs which relate to the same particular program.
  • a plurality of optical discs 1 may contain data corresponding to the same particular program. Specifically, a first portion of the particular program may be recorded on a first optical disc 1, a second portion of the particular program may be recorded on a second optical disc 1, etc., until the entire particular program is recorded on the plurality of optical discs 1. Furthermore, reproduction order data may be recorded on the lead-in areas 4 of the discs 1, and such data may indicate that the first optical disc 1 should be reproduced first, the second optical disc 1 should be reproduced second, etc.
  • the player reads the reproduction order data from the lead-in areas 4 of the discs 1 and determines the reproduction order in which the discs 1 should be reproduced. Then, the optical discs 1 are sequentially reproduced based on the detected reproduction order.
  • the microcomputer 11 determines whether or not the user has input a sequential reproduction command to place the system in a sequential reproduction mode (step S1). If the sequential reproduction command has not been input, the microcomputer 11 remains in a standard reproduction mode and performs standard reproduction functions (step S2). For example, in the standard reproduction mode, the microcomputer 11 may reproduce data from an optical disc 1 loaded in the current tray 2 of the disc changer 3. In particular, the disc 1 is rotated by the servo system 7, and the detector 8 reproduces audio and video data from the optical disc 1 and outputs such data to the signal processing system 9. Then, the signal processing system 9 processes the audio and video data, outputs the resultant video signal to the monitor (not shown), and outputs the resultant audio signal to the speaker (not shown). As a result, the data recorded on the optical disc 1 selected by the user is reproduced.
  • step S3 determines whether a plurality of optical discs 1 are loaded in the disc changer 3 (step S3). If two discs 1 are not loaded in the disc changer 3, the microcomputer 11 places the multidisc player in a sequential reproduction disable state and outputs a control signal to display an error message on the monitor (not shown) (step S6).
  • the microcomputer 11 instructs the servo system.7 and the detector 8 to reproduce the information data from the lead-in areas 4 of the optical discs 1 (step S4). Then, the microcomputer 11 analyzes the information data to determine whether the video and audio data recorded on at least two of the optical discs 1 relate to the same particular program (step S5). If the data recorded on at least two different discs 1 do not correspond to the same particular program, the microcomputer 11 places the multidisc player in the sequential reproduction disable state and outputs the control signal to display the error message on the monitor (not shown) (step S6).
  • the microcomputer 11 outputs a third control signal to the memory 10 to instruct the memory to store the information data (e.g. the reproduction order data) detected from the lead-in areas 4 of the discs 1 (step S7). Consequently, the memory 10 contains the data which informs the microprocessor 11 the order in which the plurality of discs 1 must be reproduced in order to properly reproduce the recorded program.
  • the information data e.g. the reproduction order data
  • the microcomputer 11 determines whether the user has input a command to reproduce the particular program recorded on the plurality of discs 1 (step S8). If the user has not input such command, the microcomputer 11 remains in a state is in which it continuously determines whether or not the reproduction command has been input. After the user inputs the appropriate command, the microcomputer 11 outputs a control signal to the memory 10 to retrieve the reproduction order data from the memory 10 (step S9). Then, the microcomputer 11 sequentially reproduces the optical discs 1 loaded in the disc changer 3 in the order which corresponds to the reproduction order data (step S10). As a result, the particular program recorded on the plurality of optical discs 1 is properly reproduced.
  • the microcomputer determines whether or not the user has input a sequential reproduction stop command to switch the system out of the sequential reproduction mode (step S11). If such a command has been input, the procedure ends. On the other hand if the user did not input the stop command, the procedure returns to step S8.
  • the microprocessor 11 places the multidisc player in the sequential reproduction mode only when the sequential reproduction command is input by the user.
  • the microprocessor 11 may be programmed to automatically place the system in such mode whenever a plurality of optical discs 1 are simultaneously loaded in the multidisc player.
  • the present invention retrieves information data from at least two optical discs containing at least two successive portions of the same particular program. Then, the information data is analyzed and the reproduction order of the optical discs is determined based on such analysis. Accordingly, the order in which the optical discs are sequentially reproduced is determined by the multidisc player, and thus, the ability to correctly reproduce the particular program is substantially enhanced.
